This appears to be an old tenant house (likely turpentine-related) that’s been preserved for use as a cabin. It’s located between Dexter and Dublin and is a great example of the style. Colleen Williams notes that it’s owned by the Don Hobbs family and was last used as a farmer’s market. Great idea, I think.
